Carbon has by definition 6 protons. However, its many isotopes can have anywhere from 2 neutrons to 16 neutrons, with 6 neutrons being the most common (~95% of all carbon). Carbon has by definition <b>6 protons</b>.
Well, it depends. Every isotope of a particular element has the same number of protons (by definition). All carbon isotopes have 6 protons; all nitrogen isotopes have 7 protons, all uranium isotopes have 92 protons, etc. Each element can have varying number of neutrons in addition to the protons that make the element. For carbon, for example, all carbon isotopes have 6 protons, but carbon-11 has 5 neutrons, carbon-12 has 6 neutrons, carbon-13 has 7 neutrons, carbon-14 has 8 neutrons, etc. Some of these isotopes are stable (carbon-12 and carbon-13); some are radioactive (carbon-11 and carbon-14). If you want to find out the number of protons and neutrons in an isotope, it is pretty straightforward.
